| Graco E1 Series | Ball-D1/E1 AC | Fluid flow regulation in pump system |
The Graco D07020 Kit is an OEM check valve ball replacement component designed for Graco D1 and E1 series diaphragm pumps. It ensures proper fluid flow control by sealing and regulating movement within the pump’s check valve system.
Manufactured from acetal (AC), the ball offers excellent wear resistance, dimensional stability, and compatibility with a wide range of industrial fluids. This helps maintain consistent pump performance and prevents backflow issues during operation.
It is used during routine maintenance or pump rebuilds to restore sealing efficiency, improve flow accuracy, and extend overall pump life.
